Reconstructability Analysis of Elementary Cellular Automata
Martin Zwick and Hui Shi
3-12-2010
Reconstructability analysis is a method to determine whether a multivariate relation, defined set- or information-theoretically, is decomposable with or without loss (reduction in constraint) into lower ordinality relations. Set-theoretic reconstructability ...Read More
